CUSTOM CAPABILITIES
If you’re designing with EMC in mind, please note that all of Murata Power
Solutions' ST 3 Watt DC/DC Converters have been characterized for radi-
ated and conducted emissions in our new EMI/EMC laboratory. Testing is
conducted in an EMCO 5305 GTEM test cell utilizing EMCO automated EMC
test software. Radiated emissions are tested to the limits of FCC Part 15,
Class B and CISPR 22 (EN 55022), Class B. Correlation to other specifi ca-
tions can be supplied upon request. Radiated emissions plots to FCC and
CISPR 22 for model UST-5/500-D48 appear below.
